Reverted execution attribute of shell script files in fuel-plugin sub-dir. The execution attribute was lost when these files were commited inside fuel-plugin sub-dir, and the executtion attribute of these shell script files is necessary to the build of fuel-plugin-kvm.

Upstream status: NA In Brahmaputra release, KVM plugin functionality was bundled inside the fuel-plugin-qemu. In order for easy maintenance, the KVM plugin functionality would be separated from fuel-plugin-qemu and moved into an independent fuel-plugin-kvm and keep the source code here starting from Colorado release.

2016-01-05Add guest environment setup scriptsYunhong Jiang2-0/+89
To achieve good real time and live migration performance, special setup is needed on guest environment. Two scripts are used to setup the guest environment. The guest-setup0.sh setup the environment that should take effect before the tested kernel is bringup, including install the kernel rpm, the rt-test package and modify the grub entries. The guest-setup1.sh setup the environment that takes effect after the tested kernel is up, like some sysfs entry, interrupt affinity etc. Change-Id: Icaed71e250b314723d6b1814c9ac33c10d99c6a0 Signed-off-by: David Su <david.w.su@intel.com> Signed-off-by: Yunhong Jiang <yunhong.jiang@linux.intel.com>

2016-01-05Script to create the rt-tests rpmYunhong Jiang2-0/+56
There is no rt-tests rpm on centos repo, also we need some special compile flag to enable the -a parameter. So we try to make the rpm ourselves. The version is specified as 0.96. But please notice that the Makefile in the rt-tests tree requires some key, we have to disable that requirement. So this rpm is only for OPNFV testing purpose.

Testing KVM4NFV project requires special host environment to get the best result. Two scrripts are used to setup the environment. The host-setup0.sh setup the environment that should take effect before the kernel is bringup, mostly the grub entries. The host-setup1.sh setup the environment that takes effect after the kernel is up, like some sysfs entry, interrupt affinity etc. The host-config provides the configurations.

2015-12-08kvmclock: add a new function to update env->tsc.WW-2015-52Liang Li3-16/+48
(Back port from upstream, commit id: 0fd7e098db30e302d27920487f0afec) The commit 317b0a6d8 fixed an issue which caused by the outdated env->tsc value, but the fix lead to 'cpu_synchronize_all_states()' called twice during live migration. The 'cpu_synchronize_all_states()' takes about 130us for a VM which has 4 vcpus, it's a bit expensive. Synchronize the whole CPU context just for updating env->tsc is too wasting, this patch use a new function to update the env->tsc. Comparing to 'cpu_synchronize_all_states()', it only takes about 20us.

2015-11-24Make vfio MSI interrupt be non-threaded.Yunhong Jiang1-1/+1
Currently the vfio msi interrupt is kept as IRQ thread, this is not good for NFV scenerio because in NFV scenerio, we want to inject the interrupt to the guest asap. A threaded IRQ introduces schedule latency. However, this change is like a quick and dirty and may bring potential deadlock, because the spinlock_irqsave() from eventfd_signal() is preemptible in RT kernel, which should not be held on IRQ context. But changing it to be raw_spinlock is bad because it will increase the latency a lot if the eventfd is accessed by user space. The deadlock should be ok since for vfio MSI handler is purely kernel story and the lock is a per-eventfd lock and seems no one else is using it for the vfio msi scenario.

2015-11-20Force tick interrupt and get rid of softirq magicYunhong Jiang2-44/+31
This is a backporting from upstream linux, please refer to http://marc.info/?t=142904577100001&r=1&w=2 for more information, the corresponding kernel commit is 0ff53d09642204c64842 (tick: sched: Force tick interrupt and get rid of softirq magic). The purpose of this patch is, if a tick_sched interrupt is missed, don't try to raise softirq, instead, we can simply trigger the timer interrupt. The reason is, softirq requires context switch and has much higher overhead than interrupt. Upstream status: backport 0ff53d09642204c64842 Change-Id: I70131fb85189d15972fcaa1a2a2fa190270787f9 Back-port-by: Yunhong Jiang <yunhong.jiang@linux.intel.com>
2015-11-20Add configuration to support OVS kernel moduleYunhong Jiang1-7/+13
OVS kernel module is important for NFV. The existed kernel config misses several important kernel configuration, mostly for VxLAN, which is required by the OVS kernel module. Also add the OVS as a module, so that user can use it if needed, or replace it when use the OPNFV patched OVS module.
